It might be time to dust off your digital cowboy boots.

Rockstar Games is sending the game community into a frenzy with just a couple of simple tweets. The first one on Sunday showed the Rockstar Games logo against a red background, similar to the one used in Red Dead Redemption’s promotional materials. On Monday, Rockstar posted a second image, this time showing the silhouettes of seven people against a similar red background.

Red Dead Redemption came out in 2010 for PlayStation 3 and Xbox 360. The open-world Wild West game was one of the most popular titles released for those consoles, with Rockstar shipping over 14 million copies across all platforms. It was also one of the best-reviewed games ever. Success like that usually guarantees a sequel, but fans have waited a long time without hearing much beside rumor. Now, it looks like a real announcement for something new in the Red Dead universe is coming.

Earlier this year, the Xbox 360 version of Red Dead Redemption became digitally backward compatible on the Xbox One. Red Dead Redemption is actually a sequel to a 2004 game called Red Dead Revolver. A developer named Angel Studios originally worked on the game for publisher Capcom, but Rockstar Games bought Angel Studios (which was renamed Rockstar San Diego) and the rights to Red Dead Revolver in 2002. It was a mild success compared to Red Dead Redemption, with many of the latter’s fans having never touched the original. Red Dead Revolver is now available on the PlayStation 4 via the PSN digital store.

Rockstar Games also works on the Grand Theft Auto series, which popularized the open world genre. The last entry (and Rockstar’s latest release), 2013’s Grand Theft Auto V, has shipped over 65 million copies and is one of the most successful games of all time.
